RE455 Range Extender - No Internet from devices connected to the extender.
NOTE: this is for the RE455 not the RE450.
RE455 was not available for selection in the Model list pulldown
Basical Issue - No Internet from devices connected to the extender.
Configuration
- Successfull connections to 2.4 and 5GHz local networks
- Extended network SSIDs had a _EXT suffix to make sure I was really connecting to these networks and not the main router
- Extender Network
- Static IP in the extender (192.168.1.3) inside the main router DHCP range (192.168.1.2 to 192.168.1.199)
- Subnet mask - 255.255.255.0
- Default Gateway - 192.168.1.1 for the main router
- DHCP was OFF
1st two days
- Extender had solid blue lights all the way
- Router Admin page is available via a web browser
- All extender connected devices worked fine and had non-extender (so main router) DHCP pool IP addresses
- I upload a lot of data to some cloud storage - success!!
Next 2 days
- Extender had solid blue lights all the way
- Router Admin page was available via a web browser
- All 2.4GHz, 5GHz and Ethernet extender connected devices lose outbound Internet.
- I try a great many combinations of config, factory resets and reboots on main router, extender and connected devices
- When it works:
- The extender will ONLY provide outbound Internet for connected devices if extender DHCP is enabled (with a range not conflicting with the main router DHCP range) and the extender Primary DNS + Default Gateway set to the main router 192.168.1.1
- Connected devices then receive IPs in the extender DHCP pool range, not the main router DHCP range
- However I do not want this - I need to use the main router DHCP and DNS
- When it fails
- Turning extender DHCP to OFF means that the connected devices again lose outbound Internet.
- The extender connected devices are rstill eachable and ssh/pingable from the local LAN though.
- They just can't connect to the internet (eg: ping google.com)
----
I'm an IT professional (of way too many years) and I've spent 2 days on this with many factory resets and reboots.
It really looks like a firmware bug when DHCP is disabled - basically DHCP = OFF means that the extender can't access the main router DHCP or DNS.
2 Questions
- What known firmware defects or issues are there regarding Extender behaviour when DHCP is disabled?
- I'm really on the verge of returning it and it's pretty furstrating - any suggestions to fix this??
Cheers!
